NEWYORK, N. Y., XEc Tmx 0F;

Patented March 20,1906:

alloy may be :slightly and uniforml mois 0 Be it known that GEORGE W. GESNER, detened with water or other fluid and-su jected ceased, late a citizen of the UnitedStates, did /to light pressure within the mold. Th body v invent a certain new and useful Im rovc-' must then be fired for hydrogen winch IS granted j anuary the alloy, or y trical resistance, being thereby admirably and a body of'the' powder is placed in a re 'fra-ctory open mold or saggar' and heated at a 'coheret-o form a body of the desired strength' I The resultim and preferablyslowi ment in Electric Insulators, of which t 1e following is a specification. y

In United States Letters Patent No. 604,580 ranted May 24, 1898,.No. 642,320, 30, 1900, and No. 670,775, ranted March 26, 1901, to'the said GEORGE L GESNER, are described and claimed certain processes of making alloys of iron and hydrogem'the product being in the form of a pig or ingot,powder or scale. Accordin to these patents articles consisting of the aIloy may be produced by remelting the pi s, powder or scale and pourin the liquid al 0y into mo ds by for in or re! ing heated masses of eating the powder or scale and welding and shaping it by forging or roll- Ihe present invention is abody of iron and refractor resistant to 0x1 dation and corrosion, and of ugh specific. elecfitted for use as an insulator for electric ageparatus. To, produce such an insulator; t alloy-of iron and hydrogen is finely powdered temperature of from 2,000 to 2,600? -Fahrenhei for about one hour until the particle body is removed from the mold y cooled In ashes or pulverized charcoal or in an aimealmg-furnace, and lts surface may finall be smoothed by grinding or-otherw1se. hen an HISUlILtOI of greater strength IQ'dOSlX'Bd, the powdered drogen, asset forth;

iron and hydro en body, consisting of a mixture-o a somewhat longer pee; riod than when'uncompressed. To increase the electrical resistance of the body, fire-clay may: be mixed with the o'w-, dered alloy beforelit is shaped and fired..;. 5 -\/Vl1ile, the described article is of such resistance tliat'it will ordinarily be used as anf; insulator and is therefore so termed, it will} 5611 be obvious that it may be employed'as a resister or resistance heater fon'use with" h potentials. Its resistance may also be" e5 creased by firing the body of the powdered alloy in a closed mold. 55" I claim as the'invention of the said GEORGE W. Gasman-- c 1 1'. An electric insulator or high-resistance body, consisting of-an alloy of iron and hy- 2-. An electricinsulator or hi h-resistancei body, consisting of articles 0 an alloyof itted into a coher mass, as set fort i An electric insulator or hi h-resistance body, consisting of a mixture 0 an alloy of iron and hydrogen and a material of, higher specific resistance than said ailoy, asset forthif 4. An electric insulator or h-resistance an alloy of 79' iron and hydrogen and fire-clay, as set forth. i
